The Intelligent Transportation System Using the Infrared Sensors Based on the ZigBee Protocol and Eclipse

There are more and more cars. The traffic jam cost people a lot of time on the road. This system got the number of the cars in waiting on every crossroad by the infrared sensors in the CC2530. Based on the Zigbee protocol, the routers embedded in the infrared sensors sent the information of cars in waiting to the coordinator wirelessly. Then the coordinator sent the information to the website which is developed on the Eclipse platform through the serial port. People can check the designated crossroad whether there is the traffic jam by smart telephone or the web browser. This system can release the newest information. It can be widely applied in the transportation system

A Secure and Robust Connectivity Architecture for Smart Devices and Applications

<p/> <p>Convergence environments and technologies are urgently coming close to our life with various wireless communications and smart devices in order to provide many benefits such as connectivity, usability, mobility, portability, and flexibility as well as lower installation and maintenance costs. Convergence has brought important change not only in the way we live but also in the way we think. It is the progress towards the attempt to create and to evolve new valuable services through the device convergence and fusion of in-home, office, and various environments around the personal mobile apparatus. Based on the dynamic trends of convergence, it is widely argued that the increased requirements on secure and robust connectivity between a variety of mobile devices and their applications provide us the era of real pervasive computing environment. Thus, in this paper, we present a novel connectivity architecture using RF4CE-(Radio Frequency for Consumer Electronics-) based wireless zero-configuration and enhanced key agreement approach. We analyze the security and performance of our proposed approach by the development of the prototype H/W and the construction of a testbed with CE and mobile devices.</p
